Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract The nested subset pattern (nestedness) has been widely used to explain species distributions in island and fragmented systems. Mountain sky islands serve as critical natural laboratories for understanding the evolutionary consequences of geographic isolation and climate

How much biotic nativeness matters across human demographic groups
Conservation Biology, EarlyView.Abstract Many central concepts of conservation biology—such as nativeness—are structured by ecological and social factors. However, the social consequences of using these concepts to make conservation decisions remain inadequately understood. Some researchers argue that nativeness, rather than acting as an objective proxy for important ecological ...

Attainment Pairing Effects on Cognitive Conflict in Technology‐enhanced EFL Cooperative Tasks
International Journal of Applied Linguistics, EarlyView.ABSTRACT This study examines how attainment pairing (high‐high versus high‐low versus low‐low attainment) impacts English as a Foreign Language (EFL) learner engagement during technology‐enhanced cooperative writing tasks. Seventy‐eight Chinese university learners formed 39 dyads (13 pairs per group) via Tencent Meeting.

Shiyou jixie, 2014 针对游梁式抽油机不能随油井工况自动调整平衡度和冲次，且调整不方便，造成油田设备日常管理难度较大，不利于节能工作开展的现象，研发了一种自平衡智能抽油机。该抽油机在常规机的基础上设计了一套平衡调节装置和特制悬绳器，嵌入了传感器，配套了具有特殊功能的智能控制柜，具有油井功图和电参数的采集和传输，以及根据油井工况变化自动调抽油机平衡度和冲次的功能。现场应用结果表明，该自平衡智能抽油机具有装机功率低、自动化程度高、调参方便可靠的优点，自动优化模式与工频运行模式相比，平均吨液百米耗电量由1.559 kW•h下降到1.
